Specification of Letters Patent.

Patented July 30, 1912.

Application filed March 29, 1912. Serial No. 687,091.

To all whom it may concern:

Be it known that I, DUNCAN CAMERON, subject of the King of GreatBritain, residing at Edinburgh, Scotland, have invented certain new anduseful Improvements in Paper-Ruling Machines, of which the following isa specification.

This invention relates to the ruling of paper from the web or reel butmore particularly to the ruling of transverse lines in machines of thattype wherein the paper, after being longitudinally ruled, is brought torest while the transverse lines are ruled bymeans of alaterally-traveling carriage carrying the ruling devices, said carriagemoving first from one side to the other to rule one set oflines, andthen returning after the paper has been fed forward in order to rule thenext set.

The principal object of the present invention is to provide improvedmeans for interrupting the continuity of the ruling in order to produceblank spaces or headings in the sheets, known technically as stop work.This object is proposed to be attained by placing upon the sheets wherethe ruling is to be interrupted, strips or masks of suitable materialover which the ruling devices travel when the ruling carriage isactuated, thus leaving the portion of the paper lying below the maskingstrips blank or unruled. To provide against irregularity in the positionof the blank spaces when 1 the carriage is moved in opposite'directions,

due to the momentum carrying the ruling.

devices past the edge of the masking, strips before they come in contactwith the paper, the said strips are mounted upon a frame which has asmall lateral movement automatically imparted to it each time the motionof the carriage is reversed so as to insure the absolute uniformity inthe position of the blank spaces of successive portions of the paper.

Figure 1 of the accompanying drawings represents a plan of a rulingmachine embodying the present invention. The frame carrying the maskingstrips is shown in the position it assumes while the transverse rulingcarriage is moving from right to left. Fig.2 is a similar view, butshows the shifting frame moved toward the left for.

the travel of the carriage from left to right. Fig. 3 is a transversesection through the machine showing the 'cam mechanism for moving thecarriage and shifting theframe carrying the masking strips. Fig. 1 is asimilar view but shows the frame shifted over to the left for the travelof the carriage from left to right. Fig. 5 is a side view of themachine. Fig. 6 is an enlarged transverse section, showing more clearlythe construction of the carriage and the arrangement of the rulingdevices and inking mechanism. This view shows the carriage travelingfrom right to left. Fig. 7 is a similar View, butwith the carriagetraveling fromv leftzto right. Fig. 8 is a longitudinal sectionshowingthe carriage and ruling devices and inking roller in elevation.

The same reference numerals indicate cor responding parts in each-of thefigures of the drawings.

1 is the laterally traveling carriage carrying upon the spindle 2 theruling devices 8 here shown-as disks by which the transverse lines areruled upon the paper each time the latter is periodically brought torest after having been longitudinally ruled by another set of diskscarried by the machine. The said carriage 1 slides upon a pair ofparallel guide rods 4 carried by end brackets 5, 5, and is moved fromside-toside, at the proper times, by means of a chain 6 having its endsattached to opposite sides of the carriage, and passing over sprocketwheels 7, 8, upon the frame and around a sprocketv wheel 9 fixed upon ashaft 1.0 which is supported at one end by a single bracket 11, and atthe opposite end by a pair of brackets 12, 12. The said shaft 10carries, between the brackets 12, 12, a toothed pinion 13 gearing with avertically moving rack 14: which is guided in its movement, by a flangedroller 15 upon a spindle supported between theout-er ends of thebrackets 12, 12. The rack 14 is carried by the upper end of a verticalrod 16 whose lower end is provided with a pin 17, engaging in a slot. 18in a lateral lever arm 19 mounted at its inner end upon a pivot 20. Thisrocking arm 19 carries upon one side a roller 21 which engages in a camgroove 22 in the face of a cam 22 fixed upon a revolving cam shaft 23driven from any convenient part of the machine. As the cam revolves itlifts the arm 19 which, in turn, raises the rod 16 and rack 141, whichlatter rotates the shaft 10 and sprocket wheel 9, whereby the chain 6causes the carriage 1 to move laterally inorder to rule riage.

the transverse lines upon the paper. The cam 22 is so set that it liftsthe arm 19 after the continuous length of paper has been fed forward inthe longitudinal direction and brought to rest.

The carriage 1 supports the rubber-faced inking roller 2a supplied withink from a wick or pad 25 carried by a holder 26 and kept saturated withink by suitable means, such as from a reservoir upon the carriage. Theroller 24 is provided with trunnions 27 at opposite extremities whichturn within open slots 28 in the ends of lever arms 29 fulcrumed at 30to the frame of the car- The roller is kept in contact with theperipheries of the ruling disks 3 by springs 31. The ends of the spindle2 carrying the said disks may, if desired, be mounted in yieldingbearings.

To stop or interrupt the ruling where the paper is required to be leftblank, longitudinally arranged masking strips 32 of thin sheet copper,celluloid, or other suitable material, are carried by a frame 33superimposed upon the ruling table 34 and under which the paper passes,so that the strips 32 lie upon the surface of the said paper. The saidmasking strips are attached to the frame by clamping plates 35. As thecarriage travels from side to side, the disks 3 run over the maskingstrips and leave the portion of the paper lying beneath them plain orunruled. Owing, however, to the momentum of the carriage, the disks,after leaving the masking strip 32, fall upon the paper at some distancebeyond the edge of the strip (as shown by a, Figs. 6 and 7) thisdistance being greater than that between the front edge of the strip andthe point when the disks leave the paper, (indicated by 1)).Consequently if no means were provided for correcting or compensatingfor this effect of the momentum, the edges of the blank spaces formedduring the movement of the carriage in the one direction would bedisplaced laterally with respect to the edges of the corresponding blankspaces formed on the next portion of the paper during the returnmovement of the carriage. To correct this the frame 33 carrying themasking strips 32 is arranged to be automatically given a small lateralmotion each time the carriage 1 is reversed, so that the strips arebrought nearer to the said carriage by an amount equal to the differencebetween the distance that the disks travel beyond the edge of the stripbefore touching the paper due to 'themomentum, and the distance betweenthe front or leading edge of the strip and the point at which the disksleave the paper on meeting the strip, that is, the difference betweenthe distances a, b. By this means absolute uniformity in the position ofthe blank spaces can be obtained.

To impart the lateral movement to the frame one of its rails is providedwith an upstanding lug 36 which is connected by a jointed rod 36 to avertical arm 37 upon a rocker shaft 38 which carries a horizontal arm39-connectcd to a rod 40 whose lower end is forked and carries a rollerl-l adapted to be engaged by a cam 42 on the shaft 23, said cam beingtimed to give the necessary movement to the frame 33 at the propermoment, that is, when the carriage reaches the end of its travel. Aspring 43 gives the return movement to the frame.

44 is an adjustable stop, for limiting the lateral movement of thesliding frame 33. Its position can be adjusted according to the speed atwhich the ruling is effected.

Having fully described my invention, what I desire to claim and secureby Letters Patent is 1.
